Privacy Policy — SEO Lab Chrome Extension

Last updated: 2026-08-21 Effective date: 2026-05-25

Summary

SEO Lab does not send your test records or Google account data to a server operated by WebBiz. Test data is stored mainly in your browser’s IndexedDB. Google connection metadata is stored in chrome.storage.local, and a small number of interface preferences may use chrome.storage.sync. Google access tokens are managed by Chrome Identity; SEO Lab does not store Google refresh tokens.

1. Who we are

SEO Lab is a Chrome extension developed and maintained by WebBiz (webbiz.tw), operated by Ben in Taiwan. Contact: [email protected].

2. Google data and permissions

When you connect a Google account, SEO Lab requests read-only access to:

  • https://www.googleapis.com/auth/webmasters.readonly for Google Search Console data, including queries, rankings, impressions, clicks, click-through rates, and URL inspection results for properties you can access.
  • https://www.googleapis.com/auth/analytics.readonly for Google Analytics 4 data, including available traffic, conversion, and revenue metrics for properties you can access.

The SEO Lab OAuth client has completed Google’s verification process. SEO Lab cannot modify your Search Console or Analytics resources. Use of information received from Google APIs follows the Chrome Web Store User Data Policy, including its Limited Use requirements.

3. Other network connections

  • Google Search: SEO Lab may send a keyword directly from your browser to Google Search to detect whether an AI Overview cites a target URL. This uses your browser session and does not pass through WebBiz.
  • Google Search Status Dashboard, Google Search Central RSS, and MozCast: SEO Lab reads public algorithm-event information. These requests do not include your Google account data, test records, target URLs, or browsing history.

4. Local storage

  • Test definitions, hypotheses, target URLs, criteria, and action logs are stored in IndexedDB.
  • Cached GSC, GA4, and AIO snapshots used for verdicts are stored in IndexedDB.
  • Google connection metadata is stored in chrome.storage.local.
  • Interface preferences may be stored in chrome.storage.sync and handled by Chrome according to your browser settings.

SEO Lab has no WebBiz backend for these records. It does not transmit them to webbiz.tw.

5. What SEO Lab does not do

  • It does not sell, rent, or share your data.
  • It does not include advertising, analytics SDKs, telemetry, crash reporting, or third-party tracking code.
  • It does not track you across the web.
  • It does not use your data to train AI models.
  • It does not offer or process donations in the current release.

6. Your controls

  • Export: use Settings → Export JSON Backup.
  • Delete: use Settings → Delete All Data, or uninstall the extension to remove its local data.
  • Revoke Google access: use your Google Account permissions.
  • Inspect: local IndexedDB data can be inspected through Chrome DevTools.

7. Security

SEO Lab uses Chrome’s chrome.identity API. Chrome manages the access-token cache, and tokens do not pass through a WebBiz server. If you suspect unauthorized access, revoke SEO Lab in Google Account permissions and reconnect only after securing the account.

8. Children

SEO Lab is not directed at children under 13, and WebBiz does not knowingly collect children’s data through the extension.

9. Changes

This page will be updated if SEO Lab’s data handling changes. Material changes may also be announced in the extension.

10. Governing law

This policy is governed by the laws of the Republic of China (Taiwan). Mandatory privacy and consumer protections continue to apply where required.
